Bona Fide Beauty Products

Why should I choose a glass nail file?

Our files are gentler than most emery boards and metal files. They also seal the keratin layers that make up your nails as you work, building lasting strength and health.

Oh — and did we mention they’re 100% recyclable and last up to four times as long as metal files?!  Really, what’s not to love?

Where are your nail files made?

All Bona Fide Beauty files are made in the Czech Republic from 100% genuine Czech glass of the finest quality.

We use highly specialized, state-of-the art technology to craft them, and finishing touches and final decorations are hand applied by our highly skilled staff.

When you buy a Bona Fide Beauty nail file, you are supporting a small, hard-working team of folks who take great pride in their authentic Czech-made products.

What’s so special about Czech glass?

Czech glass — also sometimes called Bohemian glass — is made using a centuries-old process and recognized globally for its superior beauty and craftsmanship. These files are the real deal!

Are your files the same as Bohemian glass files?

They are! Bohemian glass, also referred to as Bohemia crystal, is glass produced in the regions of Bohemia and Silesia, now parts of the Czech Republic. It has been around for centuries and is internationally recognized for its quality, craftsmanship, beauty and application in innovative designs.

Using Glass Nail Files

Which part of these files do I use to file my nails?

The usable part of the file is the abrasive surface that appears on both sides. It looks a bit like frosted glass.

The colored, glossy part of the file is the handle, and is designed to for a smooth grip. Hot tip? Check out our Ergo line for an even comfier file!

Are your files double-sided?

They sure are! All of our files feature a double-sided etched surface for filing your nails.

What grits do they come in?

Most of BFB’s glass nail files feature a Fine-to-Medium Grit on both sides. This grit level is higher than most emery boards, and lower grit than most metal files which tend to be overly coarse and can damage your natural nails. For an even finer grit, check out our titanium-embellished files.

What products offer your finest, most gentle grit?

Our Titanium line features our fines grit and may be better suited for extra delicate nails.

Can BFB files be used in either direction?

Yes! BFB files are gentle enough to file in either direction without tearing or shredding those beautiful nails. Just remember, a delicate touch is all you need.

Can they be used on acrylic nails?

BFB's Czech glass files are suitable for use with natural and acrylic nails. That said, if you are working with acrylics, we do recommend dipping the file in water before you begin and several times throughout the process.

Can I use your files on dip nails?

It depends.  There are a variety of dip brands on the market. Some are quite hard, others are soft. Certain dips can damage the file by wearing down its abrasive surface or leaving colored streaks behind. This is an area where you’ll want to proceed with caution.

Nail Health

Will your files help strengthen my nails?

When it comes to nails, we’re big believers in gentle care for exceptional, lasting health.

Our Czech glass files feature a fine, uniform grit that seals the natural keratin layers together as you file, leaving those nails smooth and free of jagged edges! With regular, long-term use, they can improve nail strength and appearance, and help you grow the healthy, beautiful nails we all desire!

Can I use a glass manicure file to trim my cuticles?

The area around our cuticles is delicate and nail files might be a bit too abrasive for this kind of work. Instead, we recommend Bona Fide Beauty’s Czech glass Cuticle Pusher, which some folks also call a manicure stick. It was designed for this job, after all.

What file is best for tough and thick toenails?

Our Mani-Pedi Set features a large file with a round end that is particularly good for thick, tough toenails.

Which part of these files do I use to file my nails?

The usable part of the file is the abrasive surface that appears on both sides. It looks a bit like frosted glass.

The colored, glossy part of the file is the handle, and is designed to for a smooth grip. You can check out our Ergo line for an even comfier file!

Can I clean under my nails with this file?

While everyone's nails are different, most people find that they can clean under their nails with our 2mm files.

You can also use our glass Cuticle Pusher — sometimes called a manicure stick — which has a pointed end that allows you to file beneath your nail, and clean out those hard-to-reach places.  You can purchase the Cuticle Pusher on its own, or treat yourself to either a Mani Set or Mani-Pedi Set and you’ll find one inside.

Glass Foot Files

How do I use the Glass Foot File?

The Bona Fide Beauty glass Foot file features two etched surfaces and is super easy to use!

Simply file with a light touch in any direction you’d like. For maximum polish, you’ll want to target rough skin and hard calluses with the coarse side before going in with the fine side for an ultra-smooth finishing touch.

Want a pro-level pedicure at home? These steps will deliver that just-left-the-spa result:

  1. Soak your feet for a few minutes in warm water. You can use a foot soaker, bucket, or even your bathtub. A few drops of essential oil or a sprinkle of Epsom salts will really step up the luxury and make for a great soak.
  2. After your soak, pat those feet dry with your favorite cozy towel. Now, the skin is soft and ready to go!
  3. Grab your glass Foot File and get at those problem areas with a gentle, backward and forward motion to pamper those feet and remove dead skin cells.
  4. Rinse your feet to wash away filings stuck to your feet or toes.
  5. Moisturize with a product you love.
  6. Repeat up to twice weekly (being careful not to overdo it), and say hello to healthy, touchable, smooth soles and toes!

Can I use the Foot File on my toenails?

The Foot File was made to remove calluses and dead, dry skin buildup on your feet and toes.  It is a thick, heavy file and, as such, is not generally recommended for working on nails.

That said, the finer side (which is medium grit) could be used to file particularly thick toenails or fingernails in a pinch. If, for whatever reason, you like using a Foot file on your nails, the best option is probably the extra-long file featured in our Mani-Pedi set.

Product Care

How do I keep my glass file safe?

Our Czech Glass nail files are strong, durable, and seriously low maintenance — but they are made of glass, so it is important to treat them with care!

You’ll want to avoid dropping them, or placing them under heavy objects.

How should I store my BFB nail file?

You should store your file in its original case or sleeve when you aren’t using it.

A hard case is the best option if you’d like to take your file with you when you leave the house. Simply pop your it into your travel bag, pencil case, briefcase or purse, and you can rest assured you’ll be ready for on-the-go maintenance. 

How do I clean my BFB glass nail file?

Our files are reusable, long lasting and easy to clean.  Simply rinse the abrasive surface under cool running water and let your file air dry on a soft cloth or towel.

If you’d like to protect the decorative elements, please take care not to expose your file to solvents, high temperatures, or harsh disinfectants.

Can I wash my nail file with soap?

Sure can! Just be sure to use a gentle soap.

Do these nail files wear out?

Our files are permanently etched, so the grinding elements are part of the files — not attached after the fact. They are also chemically hardened to protect the integrity of the filing surface. The result is a product that’s super durable and resistant to wear.

That said, they are still made of glass, so be sure to avoid dropping them or storing them under heavy items.

How often should this file be replaced?

Not often at all. Part of the beauty of glass files is that they don't get dull like disposable emery boards do. If you're careful with your file, it will last for years.

Will the color of the nail file ever fade?

Nope! The colors on BFB files are cured. This means that after being sprayed, the file is placed into an oven and heated. Curing ensures the color is permanent and will not fade with regular cleaning or use.

Are BFB nail files recyclable?

Yes! They are! We have a soft spot for all things beautiful — including our planet — so we try to keep our business sustainable.

For Professionals

I am a nail technician, are these suitable for professional salons?

Absolutely! Bona Fide Beauty Czech glass nail files are ideal for salon professionals. They can be washed and sterilized in-between clients.
